Abstract
Abstract A broiler for restaurants, clubs and the like, for cooking meat on both sides simultaneously on a series of spaced broiler shelves by means of intense infrared reflective heat, therefore virtually without carbon monoxide, whereby steak, chicken, fish and other foods can be cooked within a few minutes, say 3 to 12 minutes depending upon the size and type of food being cooked, and each food being cooked in an individual aluminum pan or casserole. Provision is made for adjusting both the temperature in the cooking zone, and the speed of rotation of the revolving shelves for varying the length of cooking time. A wall-insulated body or cabinet of black steel construction has an array of spaced shelves therein which are power driven respectively about a center shaft. Steel brackets on the interior of said cabinet support in fixed position gas burners, each constructed like a wheel with the burner orifices spaced along the spokes thereof. Segmented fire bricks constructed from refractory ceramic material absorbs the direct flame coming from the burner rings, so that cooking is done by infrared reflected heat at temperatures as high as 800* Fahrenheit. Loading doors for each shelf provide access whereby items may be placed on the shelf and automatically removed with the aid of an ejector bar feeding onto a conveyor.
